Condition
Rasping noise is heard (with cold engine) at end of tailpipe when RPM's are increased.
Noise cannot be heard when engine and exhaust are at normal operating temperature.
^ The system is designed to reduce exhaust system corrosion by extracting water condensation when the system is cold.
^ This design feature may cause a noticeable change in exhaust system noise level during engine/exhaust system warm-up.
Service
If a vehicle exhibits this condition:
- Inspect exhaust system for leaks at clamps and fittings.
If no exhaust system leaks are found, DO NOT replace or attempt to repair or modify any exhaust system components.
